Description
【０００１】[0001]
本考案は、変圧器などの静止誘導電器に関する。 The present invention relates to a static induction electric device such as a transformer.
【０００２】[0002]
図２は従来の静止誘導電器の鉄心の構成図であり、鉄心はコイル４がはめ込ま れた鉄心脚３と鉄心脚を連絡するヨーク鉄心５から構成されており、ヨーク鉄心 ５はケイ素鋼板１を１枚ずつ鉄心脚３に挿入積層して作られ、両側より締付金具 ６で挟み、締付ボルト７で締め付けている。ケイ素鋼板１を厚くするとうず電流 損が大きくなるため、可能な限り板厚を薄くしており、現在は０．２〜０．３ミ リメートルのケイ素鋼板１を使用している。 FIG. 2 is a block diagram of an iron core of a conventional static induction generator. The iron core is composed of an iron core leg 3 having a coil 4 fitted therein and a yoke iron core 5 connecting the iron core legs. It is made by inserting and stacking one by one into the iron core leg 3, sandwiching it from both sides with tightening metal fittings 6, and tightening with tightening bolts 7. Since the eddy current loss increases as the silicon steel plate 1 becomes thicker, the plate thickness is made as thin as possible. Currently, the silicon steel plate 1 of 0.2 to 0.3 millimeters is used.
【０００３】[0003]
静止誘導電器の鉄心の騒音を低減するためには鉄心の曲げ剛性を高くし、ケイ 素鋼板１の磁気歪による振動を抑えることが必要である。鉄心の曲げ剛性を高く するには、ケイ素鋼板１どうしを接着する方法と、締付金具６の剛性を高める方 法が考えられるが、後者は容積、重量とも大きくなり不利であるので一般的には 前者が採用される場合が多い。しかし、コイル４をはめ込み後に挿入されるヨー ク鉄心５以外はあらかじめケイ素鋼板１どうしを接着しても問題はないが、ヨー ク鉄心５は鉄心脚３のケイ素鋼板１のすきまにケイ素鋼板１を１枚ずつ挿入して ゆくので、ヨーク鉄心５を構成するケイ素鋼板１のすべてを接着すると、挿入作 業が著しく困難となる。また、コイル４に不具合があった場合コイル４を抜くた めに再度とりはずせなくなるという問題がある。このため、ケイ素鋼板１どうし は接着していないので、ヨーク鉄心５の曲げ剛性が低くなり、ケイ素鋼板１の磁 気歪による振動を抑えられず、騒音が低減できなかった。そこで本考案は、ケイ 素鋼板１をブロック状にして騒音を低減することを目的とする。 In order to reduce the noise of the iron core of the static induction machine, it is necessary to increase the bending rigidity of the iron core and suppress the vibration of the silicon steel sheet 1 due to the magnetostriction. In order to increase the bending rigidity of the iron core, a method of adhering the silicon steel plates 1 to each other and a method of increasing the rigidity of the fastening metal 6 can be considered, but the latter is disadvantageous because it increases both volume and weight. The former is often adopted. However, there is no problem in previously bonding the silicon steel plates 1 to each other except the yoke iron core 5 which is inserted after the coil 4 is fitted, but the yoke iron core 5 does not have the silicon steel plate 1 in the clearance of the silicon steel plate 1 of the iron core leg 3. Since they are inserted one by one, if all of the silicon steel plates 1 forming the yoke core 5 are adhered, the insertion operation becomes extremely difficult. In addition, there is a problem that if the coil 4 is defective, it cannot be removed again because the coil 4 is pulled out. For this reason, since the silicon steel plates 1 are not bonded to each other, the bending rigidity of the yoke core 5 is reduced, vibration due to magnetic strain of the silicon steel plates 1 cannot be suppressed, and noise cannot be reduced. Therefore, the present invention aims to reduce noise by forming the silicon steel plate 1 into a block shape.

【課題を解決するための手段】 本考案は、あらかじめ複数枚のケイ素鋼板どうしを接着し、ブロック状にした ケイ素鋼板ブロックを、鉄心脚に順次挿入積層してゆき、ヨーク鉄心を形成する 。Means for Solving the Problems According to the present invention, a plurality of silicon steel plates are adhered to each other in advance, and the block-shaped silicon steel plate blocks are sequentially inserted and laminated on an iron core leg to form a yoke iron core.

ケイ素鋼板どうしを接着することにより、板厚が厚くなったと同じ効果が得ら れ、曲げ剛性が高まり、磁気歪によるケイ素鋼板の振動が抑制され騒音が低減で きる。また、コイルに不具合があった場合でもブロック間は接着していないので 、ブロックごとに抜くことができ、容易にコイルをとりはずすことができる。 By bonding the silicon steel plates together, the same effect as thickening the plate thickness can be obtained, the bending rigidity is increased, the vibration of the silicon steel plates due to magnetostriction is suppressed, and the noise can be reduced. Further, even if there is a problem with the coil, the blocks are not adhered to each other, so that the blocks can be pulled out and the coil can be easily removed.

In addition, even if there is a problem with the coil, the blocks are not bonded together, so each block can be removed and the coil can be easily removed.
